Question about 1994 Chrysler Town & Country
I have been told the CM is in "Security-Fuel OFF" mode. I have NO codes but have a flashing dot on the digital dash just above the odometer reading. Engine cranks, no spark, no fuel pump (but I can manually close the Fuel Relay and it runs). Checked ASD relay-OK, exchanged fuel & ASD relays-no help, replaced crankshaft sensor-no help, replaced camshaft sensor-no help, checked coil-OK, checked battery & ignition power to ECM-OK. I have been told that if is model gets into "Security Mode" the only way is to replace ECM. Is that true?? What condition puts the ECM into "Security Mode"?
check your fuses if they are all good ,check all the ground wires on the engine make sure they are all making good connections,and if still not starting then its a very good chance that your PCM (computer) is bad. you can buy a used one for little money at a salvage yard.

Testimonial: "Engine ground was broke!"
Replace the ASD relay,but first check the relays powers.One power feed battery and the other one is key on.

Hi, the marks must stay aligned. If the gears are moving when you apply the tensioner, you will have to account for that by backing them up before releasing the tensioner. OR Make sure the belt is tight between the gears with the marks aligned, then release the tensioner. Rotate the engine 2 revs after adjusting the tension to make sure gears hit all marks again. You must have this right before closing the engine cover.

Hello and welcome to FixYa!
As a first course of action, I strongly suggest that you remove the positive battery connector and let it sit for atleast 5mins. before reconnecting. This will reset the system and may get it back to it's normal operation.
If the problem still persists, don't lose hope. If you happen to know someone who has a spare ECM then try a swap for I'm suspecting a computer issue here. If there's none, you may want to get one from the junkyard to cut the cost.
Hope this helps and thank you for using FixYa! Have a good one!
